Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
